Question about 1997 Dodge Ram 1500 Club Cab

1 Answer

The AC blows up through the defroster going uphill or towing.

It seems the more acceleration I use the more the AC starts blowing up through the defroster. As I let off the the acceleration it switches back to blowing where ever I had it set for.

I have this same problem with my Cherokee, it seems to have something to do with engine vacuum. Could be a faulty EGR valve.

1995 S-10, when going uphill or accelerating my AC blows out the defrosters when backing off it comes out the vents again


It is almost certainly due the drop in manifold vacuum when climbing hills or accelerating. Back in my youth windshield wipers stopped when you stepped on the gas.

Ac vacuum


There could be a vac tank problem or a vac leak.
Most american vehicles use a plastic ball or object as a vac holding tank. The tank or a vac hose can be leaking.
If the system fails, the default position is the defrosters for safety.

2003 F150 Ford ac blows out of the defrost when I accelerate


You have lost vacuum to the AC control head from the engine vacuum reservoir, go under the hood and check for damage hoses ans pinched lines going through the firewall on the passenger side.

2003 Grand Marquis LS Ultimate ac switches from blowing in dash vents to defroster vents on its own. What controls the valve and where is it located?


Does it only change when going uphill, or under heavy acceleration? Or is it just when ever it feels like it? Generally, it's vacuum controlled and on a Ford, loss of vacuum when accelerating or pulling a grade under heavy loads can be normal, causing the air to come out of the defrost. To answer your question, the blower door is located in the dash, generally behind the radio area.

Good luck!

I think the air compressor is bad in the truck


If your refrigerant level is OK and the truck blows cold air your compressor should be fine, in which case the noise is probably coming from the AC clutch which isn't too expensive or difficult to replace. If it doesn't blow cold air, switch the AC on and watch the compressor. If the clutch engages, but the compressor doesn't turn, the drive belt will squeal loudly and probably start to smoke. In that case it is the compressor which is expensive to replace. Most vehicles have an AC bypass that will temporarily cut out the compressor clutch under heavy load. If you are going uphill with the AC on or accelerating heavily you might notice warm air coming out of the vents for a short period until you let off the gas.

A/c dies when accelerating


if you are losing it blowing out of vents then it is losing vacuum and going to defrost. this would be caused by a broken vacuum line to the vacuum resevoir
